摄影测量中单一纹理的立体匹配方法研究

Research on Stereo Matching for Monotone Texture in Photogrammetry

综合边缘检测、极线几何和立体图像边缘的相关性确定图像的匹配约束和搜索范围,对相应区域进行由粗到精的渐次匹配,通过全局松弛和滤波得到高密度高质量的视差图。实验证明该方法提高了匹配效率,一定程度上消除了单一纹理的影响,所得结果可用于机械零件的三维重建。

This article set the constraints for stereo match and searching scope by edge detecting, epipolar geometry and correlation of stereo pairs, then got the matching result by iterative area match with coarse to fine strategy. Experiments prove that this algorithm promotes matching accuracy, and eliminates influences of monotone texture. The result data proves suitable for 3D reconstruction in re verse engineering.
